Motion picture optical system

An image processing optical system having an image path and an aperture stop for presenting a continuously moving image onto a surface in a manner whereby the image on such surface is immobilized in a fixed position, comprising:

• a continuously movable image carrying film strip located at a first terminus of the image path of said system;
• an objective lens located at a second terminus of the image path of said system;
• a circular rotating optical element interposed in said image path for continuously changing the angle of the axis of the portion of said path at said first terminus through a given scanning arc, said rotating optical element having a given axis of rotation lying at approximately a 45.degree. angle to the axis of the portion of said image path at said second terminus;
• first image corrector means interposed in said image path between said film strip and said rotating optical element for correcting image aberrations attributable in part to the variation of the scan angle of said rotating optical element;
• second image corrector means interposed in said image path at or near the aperture stop thereof for correcting the angular error at the aperture attributable to the tangential slope extant over the intercepted area of the aperture stop;
• and,
• third image corrector means interposed in said image path between said second image corrector means and said objective lens for correcting undesirable changes in the image path attributable to compound angle changes resulting from rotation of said rotating optical element.
